MECHANISM FOR EJECTING LINOTYPE-SLUGS.

Application filed April 3!), 1914.

T 0 (IZZ -1 0710722 it may concern.

Be it known that I, Gnonen T. TnUNnLn, J r., a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Mechanism for Ejecting Linotype-Slugs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

In the application of Harry C. Gammeter, No. 783,722, filed August 8, 1913, is described and claimed a process of making short height-to-paper line slugs having holding devices on their opposite sides, such process, briefly stated, consisting of the steps of casting a slug in a T-form with ribs on its sides, and thereafter breaking down the upper portion of the ribs and removing the lower portion of the slug to make a short slug with lugs on its sides separated from its head.

In Mr. Gammeters application No. 801,170, filed November 15, 1913, is shown, described and claimed a mechanism for easting the blank from which the finished slug is made by removing the lower portion and breaking down the side ribs, said mechanism comprising a peculiar mold for casting such slug and a peculiar ejector for removing the original slug from the mold, both these parts being adapted for mounting in the standard Mergenthaler machine.

The object of the present invention is to provide an improved ejector for such a T-shaped slug, which may so engage the shank of the slug as to remain in alinement with the same while pushing it out between the trimming knives. Heretofore this shank sometimes shifted out of alinement with the ejector blade after the slug was pushed out of the mold and into the passage between the knife holders, allowing the ejector to move idly past the slug or wedge with it in this passage.

The invention is hereinafter more fully explained and its essential characteristics set out in the claims.

In the drawings Figure 1 is a cross section of a Mergenthaler mold wheel, ejector and trimming knives; Fig. 2 is a face view of a portion of the mold wheel; Fig. 3 is a cross section through the mold and a portionof the moid wheel taken on the line -3--3 of Fig. 2, looking downwardly; Fig. i is a Specification of Letters Patent.

cross section on the line l-& of Fig. 1; Fig. 5 is a pers 'iective view of the slug cast by this mechanism showing the relative po sition of my improved ejector before engaging the same; 'Fig. 6 is a perspective view on a somewhat enlarged scale of the finished slug which is made from the slug shown in Fig. 5.

In the drawings 10 designates the usual disk-like mold wheel of the Mergen'thaler machine, having a hub 1-1 mounted on a rotatable stud 12, which is in turn mounted in a suitable bearing 1%. Rigid with this hear ing 1% is an arm 16 carrying a guideway 17 parallel with the axis of the wheel. Slidably mounted on this guideway 17 is an ejector slide 18, which, as shown, has a pin 19 in engagement with the slot of a face cam 20, mounted on a rotatable shaft 21 and adapted to reciprocate the slide.

The wheel 10 has on its outer periphery suitable gear teeth 22, and carries a mold block 24- having the usual face for the matrices, and having an inwardly projecting portion 26 fitted into an opening in the wheel. This mold block for casting a slug of T-shape is provided with a peculiarly formed slot or mold space, indicated at 27, which is adapted to form the line slug of the desired shape.

At the right or the front of the mold wheel, is a frame (not shown) rigidly carrying a trimmerknife 28 and also carrying a trimmer knife 29, which is adjustably mounted thereon. The trimmer knife 28 remains always at a fixed distance from the center of the mold wheel, while the knife 29 may be moved toward or away from the center of the wheel to allow for'difierent thicknesses of slugs.

A form of slug which may be cast by this mechanism and which my mechanism is particularly adapted to'eject, is shown particu- It has a narrow body portion or shank 30 and a T-shaped head 31 overhanging the body portion and having on its upper edge characters indicated at 32, and beneath the overhanging portion of the shank are narrow vertical ribs 33, spaced at intervals along each side of the slug extending downwardly from the under side of the head and merging with the shank about half w'ay down it.

Fig. 6 shows a line slug such as described and claimed in Mr. Gammeters application No. 01,171, filed November 15, 1913, the,

same being made from. the slug shown in Fig. 5, but cutting off the lower portion of the shank and breaking down the upper' portion of the ribs to leave lugs 62.

To form the primary slug shown in Fig. 5, the mold block 24: is provided with a narrow cavity 30* corresponding to the shank lateral cavities 31', corresponding to the head 31 and grooves 33*} corresponding to the ribs 33. In other words, the mold space is complementary to the slug shown in F ig. 5.

'lhe slide 18 fittedagainst the face 35. of the guideway 17, is suitably dovetailed into the guidewayas at 36, ill-Fig; l. Pins 38 carried on forwardly projecting portions of the head engage an ejector blade which is side of the head 31 will be suitably trimmed by the stationary trimmer knife 28 by bringing suclfinner side to-the dot and dash line A 39, in alineinent with the face the outer trimmer knife 29 is adjusted to properly trim the other side of the head 31 of the slug, and a special ejector blade is pro vided having at its rear end a face .26 resting against the face 35 of the guideway 17, and having its outer face 47 in alinement with, the outerside of the shank 30 of the slug. .The cut-away portion 49 of the ejector is formed of such length that the blade may extend through the mold a distance sufficient to push the slug past the trimmer knives and throughthe passage 50 in the frame that holds them. Atthe rear the blade is provided with suitable holes 48, Figs. 1 and i, which receive the pins 38 of the head 18. To insure the blade alining with the mold space of the mold, the blade is held against a block 51, by meansof the usual guide bar. 40 and springs 41.

It has been found that in pushing the slug from the mold by this ejector blade, that the shank of the slug abutting the forward edge of the blade sdmetimes shifts out of alinement'with the blade after the slug is pushed clear of the mold. This occurs in the space forming a passage 50 between ,the holders for the trimming knives 28 and 29, and the slugs then are either not shoved outwardly entirely clear of this passage or they wedge with't he ejector blades in the same. I have found that this may be avoided by providing a series of pins 60 in the forward edge ofthe ejector blade, each having a sharpened point adapted to engage and make smalldepressions'in the edge of the shank as the slug is pushed out. The contact of these points with the edge of the shank making slight depressions therein, as indicated at '71, Fig. 5, provides such engagement as will keep the shank in alinementwith the ejector blade until the slug reaches its outer position where it is removed by suitable mechanism, not shown.

In Figi 1 the ejector blade is shown in' broken lines in its outer position, at which point the slug is removed, the shank having been kept in aliuement with the ejector until reaching this position. In Fig. 3 the ejector is shown as just engaging the slug in the mold before ejecting the same. In Fig. 5 the slug is shown substantially in the position in which it is ejected, that is standing vertically of its length. It will be seen that in this position there is but little tendency for the shank of the slug to move laterally of the ejector blade, and the engage .ment of these points described is entirely sufficient to keep the shank in alinement until theslug reaches the position at winch it is removed.

It will be seen that I have provided an ejector mechanism for line slugs which keeps the shank of the slug in alinement with the ejector blade even after the slug has passed out of its mold. It will be noted that this is particularly desirable in casting a slug having a head or other portion thicker 7 than the shank, necessitating the passage outside of the mold as between the knives) being larger than the thicknessof the shank,

for in such a case the shank is liable to shift with relation to the ejector blade, causing trouble as above described.

Having thus described my invention, what I claim is:

1. In an apparatus for casting line slugs,

the combination of a mold for the slug, an

ejector adapted to enter the mold to push the slug therefrom, and means on the ejector for engaging the rear ed e of the slug to keep the same in alinemez t therewith. while being ejected.

2. In an apparatus for casting line slugs, the combination of a mold for the slug, an ejector adapted to push the slug from-the mold, and a sharpened portion on the ejector adapted to engage the edge of the slug to keep the same in alinement' with the ejector.

3. In an apparatus'for casting line slugs, I the combination of a mold for'theslug and an ejector adapted to push the slug from the mold by passing through the' mold space and having sharpened projections adapted to engage the edge of the slug to keep'the' same in alinement with the ejector.

4. In an apparatus for casting line slugs, the combination of a mold for the slug, an ejector blade adapted to enter the mold to push the slug therefrom, and a series of points on the forward edge of said blade engage the edge of the narrow portion of the slug.

6. In an apparatus for casting slugs havingga-T-shaped head and a narrow shank,

' the combination of a mold for the slug, an

ejector blade adapted to pass through the mold, and a series of projections on the edge of said ejector blade adapted to engagethe edge of said shank.

7. In an apparatus of the class described,

'the combination of amold having communieating cavitles for a comparatively narrow shank and a T-head, an ejector blade adapted to pass through the mold and engage the bottom of the slug shank and move with the slug out of the mold space, and means carried by the ejector blade for preventing the ejector and slug shank from coming out of alinement after the slug leaves the mold.

8. In an apparatus of the class described, the combination of a mold having a cavity for the shank of a slug and a wider cavity for a T-head of said slug, trimming knives spaced sufficiently to allow the passage of the T-head betewen them, an ejector adapted to shove against the shank of the plug and shove through the mold and between the trimming knives to deliver the slug, and means for preventing the ejector leaving the shank of the slug While the latter is in the enlarged space between the trimming knives.

In testimony whereof, I hereunto affix my signature in the presence of two Witnesses.
